Presets

This preset focuses on the lowest audible frequencies (20-200 Hz), creating a profound bass presence that can be felt as much as heard. Deep bass has been shown to have calming effects and may help with hyperacusis (sensitivity to everyday sounds) by providing gentle stimulation. The low frequencies can mask rumbling sounds like traffic, trains, or air conditioning. Some users find this preset helpful for grounding and reducing anxiety. Use at moderate volumes as bass frequencies require more energy. Best for: hyperacusis relief, grounding exercises, masking low-frequency noise, deep meditation.

White noise contains equal energy across all audible frequencies, creating a consistent "shhhh" sound similar to TV static or a fan. Research shows it can mask sudden environmental sounds that might otherwise disturb sleep or concentration. The broadband nature makes it effective for creating a neutral acoustic environment. Studies suggest white noise may help reduce the time it takes to fall asleep and improve sleep quality. It's particularly useful in noisy environments like cities or shared living spaces. Best for: general sound masking, studying, blocking traffic noise.

Pink noise has equal energy per octave, meaning lower frequencies are more prominent, creating a deeper, more balanced sound like steady rainfall or wind. Multiple studies have shown pink noise can enhance deep sleep and improve memory consolidation during rest. Its natural-sounding quality makes it less fatiguing for extended listening compared to white noise. Research from Northwestern University found that pink noise synchronized with brain waves during deep sleep improved memory in older adults. Ideal for: sleep enhancement, relaxation, long work sessions, meditation.

Brown noise (also called Brownian or red noise) emphasizes even lower frequencies, producing a deep, rumbling sound like thunder or a waterfall. The strong bass frequencies create a cocooning effect that many find deeply calming for anxiety and restlessness. Studies indicate brown noise may be particularly effective for people who find white noise too harsh or stimulating. Its low-frequency dominance can help mask bass-heavy disturbances like traffic or HVAC systems. Many users with ADHD report improved focus with brown noise. Best for: deep relaxation, anxiety relief, masking low-frequency disturbances, ADHD support.

Grey noise is psychoacoustically calibrated to sound equally loud across all frequencies to the human ear, following the equal-loudness contour (ISO 226). Unlike white noise which has equal energy, grey noise compensates for how humans perceive different frequencies. This makes it exceptionally smooth and non-fatiguing for extended listening. It's often preferred for audio testing and calibration purposes. For everyday use, it provides a balanced masking effect without any frequency range standing out. Ideal for: sound masking with minimal listener fatigue, audio work, sensitive listeners.

This preset is specifically engineered to mask human speech frequencies (300-3000 Hz), where vocal sounds are most prominent. The mid-frequency boost creates an effective barrier against conversations, phone calls, and office chatter. Research shows that intelligible background speech is one of the most distracting sounds for cognitive work. By making speech unintelligible, this preset helps maintain focus in open offices or shared spaces. The spectrum is designed to obscure speech without being overly loud. Best for: open-plan offices, coworking spaces, studying in cafés, blocking neighbor conversations.

This preset combines brown noise characteristics with a gentle roll-off of higher frequencies, mimicking the soothing sounds of ocean waves or distant storms. The absence of harsh high frequencies prevents sleep disruption and promotes relaxation. Low-frequency sounds are associated with safety in evolutionary psychology, helping trigger the parasympathetic "rest and digest" response. Studies show consistent sleep sounds can help establish healthy sleep routines and improve sleep onset. The gentle spectrum is safe for all-night listening at low volumes. Ideal for: falling asleep, staying asleep, napping, relaxation before bed.

This preset emphasizes higher frequencies (4000-16000 Hz), creating an airy, bright sound similar to gentle hissing or soft rain on leaves. High-frequency masking can be particularly effective for tinnitus sufferers whose ringing is in the higher frequency range. The spectrum is designed to provide relief without being sharp or irritating. Research suggests that targeted sound therapy in the tinnitus frequency range can provide temporary relief. Start at low volumes and adjust to comfort. Best for: high-frequency tinnitus masking, creating an airy soundscape, masking high-pitched environmental sounds.

This preset features a carefully balanced mid-range boost designed to provide optimal stimulation for ADHD brains. Research suggests that people with ADHD often benefit from moderate background noise that increases dopamine and arousal to optimal levels. The 2017 study by Söderlund et al. found that noise improved cognitive performance in children with ADHD. The spectrum avoids both the harshness of pure white noise and the heaviness of brown noise. Many users report improved focus, reduced fidgeting, and better task completion. Best for: ADHD focus support, reducing distractibility, maintaining attention during monotonous tasks.

This preset is specifically designed to help mask the perception of tinnitus (ringing in the ears). It combines a gentle high-frequency presence with a smooth overall spectrum to avoid aggravating sensitive hearing. Sound therapy is one of the most recommended non-medical approaches for tinnitus management. The goal is not to completely mask the tinnitus but to reduce its prominence and provide relief. Consistent use, especially during quiet moments when tinnitus is most noticeable, can help train the brain to pay less attention to the ringing. Consult an audiologist for personalized tinnitus management. Best for: tinnitus relief, reducing ringing perception, nighttime tinnitus management.

This preset offers a carefully balanced blend of frequencies creating a warm, enveloping sound perfect for meditation and relaxation. The spectrum is designed to be non-intrusive and suitable for extended listening without fatigue. It combines elements of pink and brown noise with gentle high-frequency presence for a complete, natural sound. The balanced approach makes it versatile for various activities from yoga to reading. Many users describe it as the "audio equivalent of a warm blanket." Best for: meditation, yoga, reading, general relaxation, creating a calm atmosphere.
